Hey guys and girls,
I've got a bit of a problem where the sump plug has stripped the thread of the sump and is now useless. I've been advised a number of things I can do to fix it, but the other half suggested fitting a keen insert as this will be the strongest solution to save the thread stripping again.
Now I've got to change the thrust bearing on the bike anyway (was the initial reason for draining the oil) and was wondering if I can remove the sump if I take the downpipes and exhaust off and then remove the clutch. Will this allow me to be able to access the sump area easily and remove it as the Haynes said remove the engine (sod that for a laugh!)
Also the Haynes said I require a special tool to remove the clutch, is this essential?

The snag with a helicoil or a thread insert will be getting it square to the sump surface. A machined steel insert threaded into a larger hole and glued with permanent threadlock would be the best way to go. If you dont have a way to hoist it, take off the tank, fairing and rear panels and lie the bike on its side. But its very likely the sump cant be taken off without taking the engine out of the frame.  |

I've just had someone tell me about gluing the plug back in temporarily to keep me going. I am a little worried about getting the thread insert square and don't want to make further problems. I have got hold of a new sump, but don't fancy removing the engine to fit it.  Wouldn't be a problem if it was a project bike where time wasn't an issue, but with it being my daily ride, it just adds to problems.  |

What about araldite steel? Is that just as good as I may know someone who might have some lying around.

Right I may be able to gain access to a hoist for the weekend fingers crossed. I have never had to helicoil or use a threaded insert before so this is all new to me. Just watched this video Now forgive me as I am no engineer or mechanic, but I realise that the keen insert is not the sort of insert you were referring to. Have you got a link to the sort of insert you mean? Also, is it a process of drilling the hole out and then using a tap to create a new thread measured to the thread of the insert and then simply glue and thread the new insert in place? I knew I should have studied engineering at university!  |

The hole is drilled out and tapped. The insert is then screwed in with thread lock (Loctite etc). On a bike sump, drain the oil, take off the tank and top plastic and lie it down on its side. You can then work on the sump bottom. Try to avoid too much debris going inside, but dont get over worried. As the job involves drilling the cutting debris should come outwards but some may get inside. Use grease on the tap for holding cutting debris take it out regularly clean and regrease. When done flush the sump with paraffin then use cheap engine oil and change that for the proper stuff. The type of kit needed is Helicoil or ezlok. These look like the vid but picture is rubbish www.ebay.co.uk/itm/STEEL-M12-X-1-75-THREAD-REPAIR-INSERTS-4-PACK-/250957361009?pt=LH_DefaultDomain_3&hash=item3a6e396f71#ht_500wt_880 |
